8 Claims.

This invention relates to code sending and recording apparatusand hasfor an object to provide an insulated wire and electrical means 7 undercontrol of a telegraph key for scraping 03 the insulation in the form ofdots and dashes whereby to effect the recording of a message.

A further object is to provide a switch contact having wiping contactwith the indentations in the wire formed by the knife and an audiblesisnal device in circuit with and controlled by the switch contact toreproduce the dots and dashes.

A further object is to provide code sending and recording apparatuswhich will be formed of a few, simple, durable and inexpensive partswhich will be easy to manufacture and will not easily get out of order.

With the above and other objects in view the invention consists ofcertain novel details of construction and combinations of partshereinafter fully described and claimed, it being understood thatvarious modifications may be resorted to within the scope of theappended claims without departing from the spirit or sacrificing anyofthe advantages of the invention.

In the accompanying drawings forming part of this specification,

Figure 1 is a side elevation of code sending and recording apparatusconstructed in accordance with my invention.

Figure 1.

Figure 3 is an end elevation of the parts shown in Figure 2.

Figure 4 is an enlarged detail elevation showing in the various views,the device is shown to com-, prise a base plate In from which rises astandard II having a shelf l2 projecting from the front face andbracedby wings I3. The shelf forms a support for tubular wire guides llwhich are ar- 5 ranged in alignment and are spaced apart at the Figure 2is a plan view ofthe parts shown in Figure 7 is a detail sectional viewshowing the characters of reference designate similar parts inner ends,Rollers II are disposed at the ends of the support I! and formantifriction bearings over which preferably enamel insulated wire II isfed through the tubular guides ll from a supply spool il to a take-upspool i3. these spools 5 being mounted on bearing arms I! and 20 carriedby the standard II. The spools are interchangeably mounted on theirshafts 2| and are held in place by'thumb nuts 22 screwed on to the endsof the shaft in the usual manner.

By now referring to Figure 5 it will be seen that between the tubularguides N there is disposed an anvil 23 which is provided in the top facewith a groove 24 to receive the insulated wire I6.

A knife blade 25 is disposed above the anvil and is provided midwaybetween the ends with a curved sharp edge 23 which receives the wirewhen the knife descends and scrapes off the insulatlon from the wire asthe wire passes along 20 the anvil from the supply spool to the take-upspool. The knife is provided with a U shaped arm 2'! which embraces theshelf or support i2 and one leg of the arm is equipped with an armature28 which is disposed below the support in 25 vertical alignment with theknife. The other leg of the arm is considerably thickened above theknife blade as shown at 23 in Figs. 5 and 6 and is provided with hingeears 30 to receive the pivot pin 3i of an arm 32 which is pivotallyconnected 30 at the upper end to a spring arm 33 as shown at 34 in Fig.5. The arm 33 is adjustably mounted upon a bracket arm 35' carried bythe shelf or support l2. The knife is thus hung or suspended over theanvil by the spring arm 33 which nor- 35 mally holds the knife bladeraised or in released position. The spring arm 33 is adJustably confinedin a slotted enlargement 36 in the upright arm 35, by means of a setscrew 31.

a Underneath the shelf or support ii an electromagnet 38 is secured tothe standard II by means of a bracket 39. The core 40 of theelectromagnet is disposed in vertical alignment with the armature 28 andwhen-the electromagnet is energized the armature is attracted and movesthe the wiring knife downwardly to intercept the insulated wire duringits travel along the anvil and scrape the insulation from the wire. Whenthe electromag net is deenergized the spring arm 33 moves the knife outof contact with the wire into raised or released position. The terminalwires ll of the electromagnet are led to a Socket 2 carried by aninsulating base 43 mounted on the base plate I0. I

The terminal wires '44 from a telegraphkey 4i and battery It may be plkged into the socket 42 as shown diagrammatically in Figure 9 so thatwhen the key is depressed the knife will be held in contact with thetraveling insulated wire II,

and when the key is released the electromagnet substituted for the knife2! by removing the pivot pin II to disengage the arm 21 from the arm 32,and the pivot pin may now be passed through the hinge eyes ll which areon the switch contact 41 to secure the contact to the arm If. A-flexible wire." is connected at one end as shown at Ii to the spring arm33 and the opposite end is equipped with a plug I! which may be pluggedinto a socket il in the insulating base ll to connect the contact incircuit with a buzzer I! or other audible signal device as showndiagrammatically in Figure '9. 'I'he switch contact 41 is spring pressedby the arm a to have wiping contact with the wire It as shown in Figure8 and during travel of the wire the guide tubes orientthe wire todispose the indentations underneath the contact so that theindentations, corre- .':sponding to the dots and dashes, will operatethe buzzer II to reproduce the code message.

A motor I is mounted on the base plate It and the pulley ll of the motoris connected by abelt II toa pulley 51. on the shaft II of the take-upspool II. The motor may be wired to a socket It on the insulating baseso that a flexible cable orcord from the house circuit may be plugged into operate the motor. A brake N,- as best shown in Figure 1, is mountedon the base plate I. and frictionally engages the rim of the supp y 9001"to retard the speed of this spool while the wire I6 is being unwoundtherefrom so that the wire will be held taut at all times during travelover the anvil fl.

From the above description it is thought that the construction andoperation of my invention will be fully understood without furtherexplanation.
